:wink: Hello,

Incredimail is the default mail program and Web Window Killer is a pop up blocker.

I have done as you have suggested & reinstalled Avast. I had to do this several times as there appeared to be a bad link.

When I was satisfied I had received a good download as soon as I ran the Mail Protection Wizard I received the message “a program bug or invalid data entry”. Yes this is a message box to report what had happened leading upto the program crash. The crash message is from C:\Program Files\Alwil Software\Avast4\DATA\log.

I have run the Mail Protection Wizard again and received the same message box.

Avast seems to be running OK except for mail scanning.

On a slightly different topic ZoneAlarm doesn’t recognise Avast as the resident anti virus program, is this normal? 8)
